Changing the colors of lxterminal

How can I change the default colors of the lxterminal in Lubuntu using .bashrc?

To change what color the prompt use (by editing .bashrc), please read Changing colors for user, host, directory information in terminal command prompt (as in Jobin's comment).

For example:

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;35m\]\u\[\033[01;30m\]@\[\033[01;32m\]\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ \[\033[00;36m\]'

Look for the \[\033[00;36m\] near the end. It sets the color of the commands you type. Look at this answer for color number reference.

If you mean the "default colors" as the foreground color (usually white or black) then you can change it in the settings screen of LXTerminal. Note that this is saved to ~/.config/lxterminal/lxterminal.conf, not .bashrc.

If you mean the appearance of each color (ex. you want to make dark blue to something brighter), then unfortunately you can't with LXTerminal because its color scheme is hardcoded. Marty Jack from LXDE forum wrote this:

At this time we do not offer any more customization than foreground/background. You are encouraged to run any terminal emulator that meets your needs.

If you need lightweight terminal that supports color scheme customization, xfce4-terminal will do the job. To install it type the following command in LXTerminal:

sudo apt-get install xfce4-terminal

You can change the default colors of LXTerminal quite easily. I don't know if this change was brought out by a recent update or not, but now I can run LXTerminal with a custom color scheme. I use LXTerminal as a default terminal for programming in vim with colors.

Using the scripts from base16-shell, you can set the colors for LXTerminal. Just source the script in your bashrc(orzshrc) and the appropriate colors will be loaded.

Add the following to source the script :

COLOR_SCHEME = "/path/to/colorscheme/script"
[[ -s $COLOR_SCHEME ]] && source $COLOR_SCHEME

I changed the script to use the Solarized-dark colorscheme for LXTerminal.

# Colorscheme : Ethan Schoonover(http://ethanshoonover.com)

if [ "${TERM%%-*}" = 'linux' ]; then
    # This script doesn't support linux console (use 'vconsole' template instead)
    return 2>/dev/null || exit 0

However the 256 color space is not properly changed.
